L ettersPatent No. 92,343, dated July 6, 1869.

'.lheSchedule referred to in these Letters Patent and making part ofthe same.

To all whom it may concern.-

Be it known that I, Moses HVNIcHo'Ls, of Han` cock, in the county of Delaware, and State of New .accompanying drawing, forming part of this specification.

This invention relates to al new and useful improve ment in means for securing and protecting jars or pots of butter, lard, preserved meats, fruits, desiccated vegetables, and other articles, which are placed in glass or stonejzn-sfurpots, ihr-preservation from tlre'jair and for transportation; and consist-sin the employment ot two or more right and left-handed screw-rods for drawing together plates of metal, or top and bottom pieces ot' wood, betweenwhich the jar or pot is confined, as hereinafter more fully described.

In the accompanying sheet of drawing- Figure 1 represents a vertical section through the line :v-a of iig. 2, showing tbe two wooden pieces or squares, connected together by the screw-rods, between which the `iar is secured.

Figure 2 is a horizontal section. of fig. 1, through the line 1j-y.

Similar letters of reference indicate corresponding parts. i

A represents the jar, which is made of glass or of stone, or of other suitable Inaterial'ibr properly prel serving butter, lard, and other similar articles.

For butter, the jar should be made, as represented in the drawing, tapering from the bottom to the top, so that, by inverting it, the contents kwill leavethe jar in a compact form, corresponding with the inside of the jar.

B represent pieces of wood or board, of suitable thickness'and size i'orenclosing the jar, which pieces may have cross-strips C fastened to them, crosswise of the grain, to prevent` the warping of the boards, and to give a good hold ihr the screws.

D D represent rods, with each arig thread o n one end, and a left-hand thread on the other end, with corresponding screw-threads cut in the strips C, and also in the pieces or boards B, if desired.

lhe butter being properly packed, and the top of the jar being protected in any lsuitable manner, the jar is placed between the top and bottom pieces B B, and the screw-rods are revolved, one of each of their ends having a right, and the other end a leftband i screw. l

It will be seen' that the etiect will be to draw the top and bottom pieces together as vtightlyas may be required. v

Any elastic packing o'r material-on the top vot the jar will be compressed, so that the air will be eiectually excluded, while the jars may, when thus p rotected, be kept for any desired length of time, or trans ported to market, without danger of being broken by contact with'each other. v

For large jars, three or four of the screw-rods may be used.

In case four are used, one of them' may be shorter than the rest, so as to be more readily detached for removing the jar. v

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, isv The combination, with the jar A, of the right and left-hand screw-rods D D, and the top-and bottom pieces B B, as herein described, for the purpose speciiied.
